(b) In series combination charge $Q$ is same. So charge on $2\,\mu F$ capacitor is
$Q = {C_{eq}}V = \left( {\frac{{2 \times 8}}{{2 + 8}}} \right) \times 300 \times {10^{ - 6}}$$ = 4.8 \times {10^{ - 4}}\,C$
$Q = {C_{eq}}V = \left( {\frac{{2 \times 8}}{{2 + 8}}} \right) \times 300 \times {10^{ - 6}}$$ = 4.8 \times {10^{ - 4}}\,C$
